HVAC & Plumbing Services in Duluth, MN

A big share of Duluth's housing stock went up before World War II, especially in neighborhoods like Congdon, Chester Park, and Lincoln Park, and those homes were built around hot-water radiator heat. Boilers are great systems when they are maintained. We repair and replace them, and we are just as happy keeping a good one alive as swapping it.

Yes, with the right equipment. Cold-climate models paired with gas backup handle Duluth's below-zero stretches, and the lake effect actually helps in shoulder seasons because temperature swings are milder near the water. Details on our heat pump services page.

Most often it is a duct system that was converted from gravity heat and never rebalanced. Those old octopus systems relied on warm air rising on its own, so the runs are short and fat downstairs and starved upstairs. Balancing dampers, a return in the right place, or a small zoning change usually fixes more than a bigger furnace would.

Yes, and you do not need ductwork to do it. A ductless system puts a head in the rooms that actually get hot, usually the upstairs bedrooms, and leaves the boiler alone to do what it already does well. It also gives you efficient shoulder-season heat, which is most of the Duluth year.

Almost always a repair. Banging in a hot-water system usually means trapped air or a circulator problem; in a steam system it usually means condensate that cannot drain back because of pitch or a bad trap. Neither is a reason to tear out a boiler that is otherwise sound, and we will say so rather than quote a replacement.
